BENNETT L. SMEDLEY, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN PILL-MACHINES.

Specification forming part of Letters Patent No. 214,849, dated April29, 1879; application filed February 27, 1879.

To all whom it may concern:

Be it known that I, BENNETT L. SMEDLEY, of the city and county ofPhiladelphia and State of Pennsylvania, have invented a new and usefulImprovement in Apparatus for Making Pills, &c., which improvement isfully set forth in the following specification and accompanyingdrawings, in which Figure 1 is a top or plan view of the apparatusembodying my invention. Fig. 2 is a central longitudinal verticalsection thereof. Fig. 3 is a side elevation of a detached portion, andFig. 4 is an end view thereof.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of a support, with sockets for the mold, and alever, both arranged longitudinally, whereby the pill or powder mayfirst be compressed and then ejected by the said lever.

It also consists of a support formed with a socket to receive the moldduring the compressing operation, and a socket to sustain the moldduring the discharge of the pill, and provided with a receptacle for thepills, &c., whereby the latter are most conveniently accessible.

Referring to the drawings, A represents a block of wood or othermaterial forming a base, to one end of which is secured a standard, a,having pivoted to it a lever, B, which extends longitudinally, or in thedirection of the length of the base.

0 represents the mold, consisting of a barrel, plunger, and bottom die,all of which have been in common use; and D represents a support for themold, which is preferably formed of cast metal, so as to possess thenecessary strength, and consists of a solid portion, 1), wlth a socket,c, and a top portion, d,.formed with depending side walls 0, and havinga socket, f, and an opening, f, which leads to the space formed by thewalls 0, into which space is fitted a drawer, E, the portions band 01being at opposite ends of the support.

The supportD is secured to the base A, and extends in the longitudinaldirection thereof, similar to the lever B.

The operation isas follows: The mold O, with the plunger removed, isplaced in the socket c, the powder is introduced into the barrel, andthe plunger is then restored, as is I well known. The plunger is in suchposition that it may be depressed by the lever, whereby the powder willbe conveniently and powerfully compressed, as is evident. The lever isnow raised and the mold lifted from the socket 0, while the bottom dieremains therein, the faces of the dies being highly polished or somewhatgreased, to prevent sticking of the pill thereto. The mold is thenplaced in the socket f and the lever depressed, whereby the pill isforced from the barrel of the mold and injected through the opening finto the drawer E, when employed, or the space formed by the walls 0.The mold is then returned to the socket c.

It will be seen that the same lever both compresses the powder anddischarges the pill, and is rapid and powerful in execution.

It will also be seen that the pills are not scattered, but are collectedwithin easy access at the top of the base, and. that a convenient handapparatus is produced.

I am aware that pill-machines have been variously constructed, and thatit is not new to employ detachable molds and barrels there- In.

I am also aware that the bases or supports of some pill-machines andapparatus have been formed with openings leading to the bottoms andsides thereof for removal of the pills; wherefore I disclaim suchfeatures.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The base A, in combination with the double socket-support D, securedto the top of the same, and the lever B, hinged at one end thereof, bothsupport and lever extending in the longitudinal direction of the base,substantially as and for the purpose set forth.

2. The support D, consistingof the portion b, with socket c, and topportion d, having depending side walls 0, socket f, and opening f,substantially as and for the purpose set forth.

BENNETT L. SMEDLEY.
